/** Three window-bound setup effects bundled together:
 *  - Linux WebKitGTK smooth-scroll per-window (re-applies after auth hydrates
 *    so preloaded/hidden mini matches the Settings toggle).
 *  - Initial expanded-size restore: Rust always builds the window at the
 *    collapsed size, so on cold start with queueOpen=true we resize once.
 *  - Always-on-top reapply on mount and on focus: WMs silently drop the
 *    constraint after Hide/Show cycles, so we re-assert it whenever the user
 *    actually brings the window to the foreground. */
